I wouldn't bother because of the age of the brass, but, if 'RicKrager' wants to experiment with this brass, he could pull the bullets and salvage the powder.

The (primed) partially collapsed cases could be 'fire-formed' with a suitable pistol-powder load and paper towel wadding.

Once 'fire-formed', the case necks could be annealed, trimmed, and neck-sized, to ready them for 'reduced-load' use.
